Here it is, the first DSi CFW!

Video by Alex S (with TWiLight Menu++ (previously known as DSiMenu++ and SRLoader) installed):


Video by @Apache Thunder (When RocketLauncher was planned for a release. With WarioWare Touched (DSiWare version) installed.):


(NOTE: Since hiyaCFW has been released a few days ago (as of posting this), and no official thread has been made, I decided to go and make it, despite not making the actual patches for it. )

With this CFW, you can run custom DSiWare, alongside region free and 3DS-exclusive DSiWare (WarioWare Touched), on your SD card, via NAND to SD redirection!
You can also run blocked flashcards (such as R4 Ultra).

FAQs
Q: Can I use a custom splash for hiyaCFW?
A: Yes you can. Place it at "sd:/hiya/" and name them "splashtop.bmp" and "splashbottom.bmp". Make sure they're actually saved as .bmp files, with the size of 256x192, with no color space info, and is 16-bit (A1 R5 G5 B5, or X1 R5 G5 B5). .gif files will also work instead of .bmp files.

no luck. i tried both with wifi on and without, with it just says i need to update, without well, its says there's no internet. what should i try next? just update?

Update, then downgrade using ugopwn

Just update and you will see the data management software. Then follow the guide.
Assuming you have flipnote studio on your USA DSi.

There is no reason to downgrade. unlaunch.dsi does not require the user to be on any specific OS version to function properly.

Except the last version softbricks you for using FW 1.4.5.

thanks for the help. updating and entering the dsi shop did the trick

I have two DSi's running 1.4.5 with unlaunch.dsi v0.7 and HiyaCFW v1.3.1 functioning just fine.

Have you tried running SysNAND? That literally does not work, and there's no possible way for it to work if you're using v0.7. It's been fixed in v0.8, but it still stands that it broke at least one firmware.

Oh, no, I haven't. I updated from v0.6 to v0.7, never booting to sysNAND in the process. Sorry for spreading false information. Though I guess that's no longer the case as of approximately eight hours ago.

damn, i already had it downgraded because i wanted to use ugopwn to install a couple backups, but my impatient ass could have waited a couple months and not risk brick

what SD are you using? i mean the model, brand, capacity, etc

 

[Cmdutka86]

Initially a Toshiba 2GB SD-M02G (the one that came with my launch 3DS)

And I've tried a PNY 2GB with seemingly the same model number.

I have also tried a couple of 4GB cards on the off chance with no luck.

I have used SD formatter V4.0 as suggested earlier in the post nothing has helped.

sometime between now and the heat death of the universe

Yeah seems about right

 

[Jake336612]

So I followed a guide and the Hiyacfw screen comes up on my dsi, but after that it just stops on a white screen forever. Any idea whats wrong?

I am attempting to install unlaunch on 2 XLs, but I keep getting an error "mismatch in fat copies please repair that before install unlaunch". I'm not clear on what FAT copies its referring to or how to fix them. They are both 1.4U.

i got it working by making my 4gb card's only partition a 1.95 gb one
